How did classical music in movies and TV become synonymous with villainy?

Although classical music has long been associated with a prosperous milieu, the massive media and advertising industries over the past 50 years transformed the image of the concert hall from a beacon of artistry into an emblem of exclusion. In the 1990s, more daring directors—such as Jonathan Demme in The Silence of the Lambs, Luc Besson in Léon: The Professional, and Stanley Kubrick in Eyes Wide Shut—started deploying orchestral music as an analogue for a darker side of human greed. From the burning core of Kubrick’s pure molten genius, imitators extracted two tepid trends for future films: orchestra-loving evildoers and classical soundtracks for bloodshed.
